Abstract (en)

[origin: WO9954055A1] A segmented die assembly (10) comprising a plurality of side-by-side and separate units. Each die unit includes (a) a manifold segment (11A-11D) having an internal gear pump (15A-15D), (b) a die module (12A-12D) mounted on the manifold segment, and (c) a recirculating module (2A-2D) mounted on the manifold segment. The manifold segments (11A-11D) are interconnected and function to deliver process air and polymer melt to the modules (12A-12D). Each die module (12A-12D) includes (a) a fiberization nozzle (13), and (b) a valve (21) for controlling the flow of polymer therethrough. The gear pump (15) of each manifold segment receives a polymer melt and delivers it either to the die module (12) (with its valve open) or to the recirculation module (2) (with the die module valve closed). Polymer melt flowing through the die module (12) is discharged as a filament or filaments onto a moving substrate (9) or collector. On the other hand, polymer flow through the recirculation module (2) is returned to the polymer melt hopper or reservoir for recirculation through the die assembly (10).
